Preferably, in the step (3), accelerate stirring 1000-1200 to turn/min, determine thin after accelerating stirring 30-40min Degree, such as fineness are unqualified to be completed by increasing by one grinding step.
Preferred embodiment, the antifreezing agent is specially ethylene glycol, and coalescents specifically use C-12 coalescents, levelling agent It is specific to use 003 levelling agent, thickener specifically to use 112 thickeners, titanium dioxide specifically to use R606 titanium dioxides.The barite Powder is from the blanc fixe more than or equal to 1000 mesh.
In the fireproof coating preparation method, using water as solvent, the first step is thickened coating to the aqueous solvent first Plus adhered modification, specially under the stirring action of relatively low rotating speed, first putting into HEC celluloses makes it tentatively uniformly be mixed with water Close, afterwards step 2, under high-speed state, input AMP-95 amine neutralizers are fully acted on HEC celluloses, make HEC fibers Element is fully dispersed in aqueous solvent (to transparent without particle), so as to realize water thickening power, possesses certain viscosity, in subsequent step The scattered shearing force of high speed can be lifted, beneficial to simplified manufacture craft.Step 3, first under moderate rotation state, first successively Put into specific several conven-tional adjuvants (including MC preservatives, coalescents, antifreezing agent, NXZ defoamers, CF-10 wetting agents, 2400 Dispersant), stir, then input filler auxiliary agent (titanium dioxide, blanc fixe) and principal component (APP, melamine successively Amine, pentaerythrite), after preliminary uniform mixing, stirring is further accelerated, so far beneficial to each component, fully effectively dispersion and fineness meet It is up to standard.Step 4, stirring is slowed down, and is slowly put into BLJ-660MV emulsions and is coordinated 345 defoamers, and BLJ-660MV emulsions are fully mixed Synthesis film plays froth breaking and acts on simultaneously simultaneously, by 345 defoamers, is finally segmented input levelling agent and thickener successively again.
Fire protection flame retarding principal component is made up of APP, melamine, pentaerythrite and BLJ-660MV emulsions, polyphosphoric acid Ammonium and pentaerythrite are arranged in pairs or groups, and used as foaming ingredient, foaminess is good, and melamine is decomposed as carbon component, carbonization, and anti-flammability is excellent, BLJ-660MV emulsions are consequently formed effective carbonaceous foam heat-insulating flame-retardant layer, for closing protected thing as sour composition Body, plays prevention heat transfer, prevents object burning, it is to avoid temperature is raised and causes steel construction intensity to decline problem, heat-insulating flame-retardant Fire protecting performance is excellent, and nontoxic smokeless security is good.Further, using BLJ-660MV emulsions, not only beneficial to coordinate other main into Fire-retardant fireproof effect is waved in distribution, and it also as anti-corrosion spy's agent, tack is good, plays excellent antiseptic and rustproof anti-mold effect.
This case fireproof coating is added with two kinds of defoamers of NXZ defoamers and 345 defoamers in preparing, and both defoamers exist The different time sections of making play different bed materials froth breaking effect.It is high that NXZ defoamers are used for step 3 kind fire protection flame retarding principal component Bubble elimination effect in fast dispersion process.345 defoamers are used for BLJ-660MV emulsion dispersions process in step 4 and play auxiliary Froth breaking is acted on.Further, HEC celluloses and AMP-95 amine neutralizers coordinate and play certain thickening power in step one, itself and step Thickener plays the effect difference of thickening in four.HEC celluloses and AMP-95 amine neutralizers coordinate primarily directed to aqueous solvent Thickening plus viscous effect, thickener are the overall polishing thickening power to whole fireproof coating system for the later stage.So coordinate and set Meter, not only makes whole manufacture craft become simple, efficient, but also optimize the combination property of fireproof coating.
Specific embodiment one
A kind of preparation method of steel structure aqueous fireproof coating, processing step is as follows：
(1), put into water in a mixing bowl, start 500 turns/min of mixer, be slowly added into HEC celluloses, stirring to surface without Powdery；
